"The Retsch Ultra centrifugal mill is the one "grinder" that gave us the particle size and hence the best analytical result ( oil content) in a variety of oilseed sample types. Over 30 years in the laboratory, allows me to call the Retsch mills/ grinders as the "gold standard" when it comes to sample preparation." Douglas DeClercq DRD
Chip size is generally controlled by feed rate. The chip size can range from approximately 2 inches (5 cm) down to less than inches ( cm) in size. Once the firststage grinding or chipping is completed, the feedstock is milled to the desired particle size. Hammer mills are common equipment for this stage of mechanical preprocessing.

In granulometry, the particlesize distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
